Friday afternoon, 1 October. Location: one of the most vibration-free places in the world. In this setting, Leiden top scientists launched Quantum Leiden. For decades, researchers at the Faculty of Science have been investigating quantum technology at the highest level and also have been brainstorming…

No less than six Leiden projects received a grant for quantum research from the national growth programme Quantum Delta NL and the NWO. After all, in order to boost quantum technology not only industry is needed, but also science. Research towards new sensors, faster algorithms and quantum materials,…

Researchers found a way to run programmes that should be impossible to carry out on an imperfect quantum computer. Such programmes are very computationally demanding and the quantum computers that currently exist are not yet up to that task. Unless you use a clever trick, Simon Marshall and Vedran Dunjko…

Quantum Delta NL, a research programme in which Leiden University participates, has been awarded 615 million euros from the National Growth Fund to help develop the Netherlands into a top player in quantum technology. This has been announced at the presentation of the honoured proposals in The Hague…

The Western Mediterranean is a key region to understand human dispersal events within and out of the African continent as well as for the eventual replacement of Neanderthals by anatomically modern humans during the Pleistocene. Central to any conclusive interpretation of archaeological and palaeoclimatic…

Leiden physicists Tjerk Oosterkamp and Dirk Bouwmeester have received a 1.3 million euro Science-Groot grant from NWO to catch a mystery at the core of quantum mechanics, together with Amsterdam physicist Jasper van Wezel.

The 18.8 million euro NWO Zwaartekracht grant for quantum software which Amsterdam, Delft and Leiden landed collectively, means for Leiden University among others the appointment of two new permanent scientific staff members, who will each form their own research group, divided among Computer Science,…

Astronomer Koen Kuijken and physicist Tjerk Oosterkamp have each been awarded a major subsidy by NWO. The funding will allow them to construct new research facilities.

The second quantum revolution is in full swing, bringing all kinds of new technologies to within reach, and offering many opportunities as well as challenges. Leiden and Delft decided to join forces.

Physicists in Leiden have built a microscope that can measure no fewer than four key properties of a material in a single scan, all with nanoscale precision. The instrument can even examine complete quantum chips, accelerating research and innovation in the field of quantum materials.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

State secretary Mona Keijzer received the National Agenda on Quantum Technology from Robbert Dijkgraaf on 16 September. With this agenda, Dutch knowledge institutes and high-tech companies identify what is needed to maintain and strengthen the Dutch pioneering role in this area. Researchers from Leiden…

Leiden physicist Julia Cramer receives 50 thousand euros in funding for 'Let's talk about quantum', a research project on communication about quantum computing. A project for high school students by education expert Henk Buisman is also included in the NEWA ELSA funding.

This minor provides a representative and coherent overview of the entire discipline of Psychology.

In the weekly magazine “Mare” from Leiden University, an interview with the Leiden statistics prof. dr. Richard Gill has been published recently about his contribution to the Delfts quantum-experiment.

Intro Week is your way to settle into LUC! You will get to know your fellow exchange students, join activities alongside the Class of 2029, find your way around the city and LUC. Intro Week 2026 will take place from 17 - 21 August 2026. More details and the schedule are to come!
